上海市宝山区市售水产品中副溶血性弧菌的快速定量风险评估

Swift quantitative risk assessment of Vibrio parahaemolyticus in commercially available aquatic products in Baoshan District of Shanghai

目的了解上海市宝山区居民因摄食水产品而导致的人群发病人数和发病概率,掌握疾病发生的关键控制环节,为食源性疾病防控提供数据支持。方法采用快速微生物定量风险评估(sQMRA)对2018年上海市宝山区市售水产品中副溶血性弧菌进行风险评估。结果人群摄入受副溶血性弧菌污染的鱼类后感染308人,发病31人,发病概率为(1.53×10^-5)%,摄入虾类后感染2826人,发病283人,发病概率为(1.39×10^-4)%,不完全烹调和交叉污染是导致人群感染副溶血性弧菌的主要途径。结论居民摄入虾类水产品导致人群发病的人数和发病概率均较鱼类高,虾类是需要重点监管的水产类别。针对烹调方式和交叉污染需采取针对性的防控措施。

Objective To understand the case number and the probability of diseases caused by the intake of aquatic products in Baoshan District,master the key links of disease control,and provide data support for prevention and control of foodborne diseases.Methods The swift Quantitative Microbiological Risk Assessment(sQMRA)tool was used to assess the risk of Vibrio parahaemolyticus in commercially available aquatic products in Baoshan District of Shanghai in 2018.Results 308 people were infected after eating fish contaminated by Vibrio parahaemolyticus,there were 31 patients,and the probability of illness was(1.53×10^-5)%.2826 people were infected after eating shrimp,there were 283 patients,and the probability of illness was(1.39×10^-4)%.Incomplete cooking and cross-contamination were the main routes causing the infection of Vibrio parahaemolyticus in the population.Conclusion The case number and probability of diseases caused by the consumption of shrimp are higher than those of diseases caused by the consumption of fish,so shrimp is the aquatic product that needs to be supervised.Specific prevention and control measures should be taken for cooking methods and cross-contamination.
